Pretty much as I expected, except for the Tamron. Even with the
criticisms, these lenses are vastly superior to similar lenses of
twenty or
even ten years ago. You can't go wrong with any of 'em.

Nope, and I tried the Nikon and bought the Tokina. I rarely used it, so
I gave to a friend...and now I miss it so I may try the Sigma. I don't
shoot a ton of wide angle though, so it's not high on my list. Things
have come a long way and you where it really shows is with cheaper
lenses like my 28-200G Nikkor which is capable of Macro, shows no CA
and is ultra sharp...almost as sharp as a 50mm prime!
